During Sony's Gamescom briefing, Andrew House announced that PS3 players who purchase select software will have the ability to upgrade to the PlayStation 4 version for a "significantly discounted price."

House confirmed a number of games will be available for the "limited time" offer, including Call of Duty: Ghosts, Assassin's Creed 4: Black Flag, Watch Dogs and Battlefield 4. Activision, Ubisoft, EA and Warner Bros. were noted as publishers partnering with Sony on the upgrade initiative. It's unclear if the program will be available worldwide.

Unlike similar retailer offers revealed for Xbox One software earlier this week, Sony's plan is to offer the discounted games through its own digital storefront.

PlayStation 4 launches in North America on November 15 and in Europe on November 29.
